THOMAS LUND, 0F BEVERLY, MASSACHUSETTS, ASSIGNOR T0 UNITED SHOE MACHIN-ERY CORPORATION, OF PATERSON, NE'lV JERSEY, A CORPORATION OF NEW JERSEY.

DIE.

To all whom it may concern: Be it known that I, THOMAS LUND, a citizenof the United States, residing at Beverly, in the county of Essex andState of Massachusetts, have invented certain provements in Dies, ofwhichthe following description, in connection with the accompanyingdrawings, is a specification, like reference characters on the drawingsindicating like parts in the several figures.

This invention relates to dies, and espe cially to cutting dies adaptedto bevel one or more of the edges of the piece cut.

The object of the invention is to produce a simple and efficient deviceof this character.

A feature of the invention consists in the provision of a member havingcutting edges and being adapted to carry other elements of thedevice,there being a cutting member movable relatively to the carriermember, and means movable upon the carrier member to actuate the cuttingmember while the carrier member is producing its cut. In the form of theinvention hereinafter disclosed, there are cutting edges on oppositeside walls of the die, between which walls cutting members move inopposite directions. I prefer to mount the cutting member, or cuttingmembers if more than one is employed, in a guideway in the carrier wallembodiment of my invention, the die has side and end walls, both withcutting edges, and the cutting member is movable between the side wallsinto proximity with the edge upon an end wall. Two oppositely situatedcutting members are shown cooperating with the respective end walls.

Still another feature concerns means for adjusting the actuatingmemberto vary the operation of thecutting member. This may beaccomplished by changing the relation Specification of Letters Patent.

of the inclined surface of the actuating member, such change beingpreferably effected by a contact member adjustable upon the actuatingmember.

In the accompanying drawing,

Figure 1 is a side elevation of a beveling die disclosing my inventionin a particular form, parts being broken away;

Fig. 2 is a perspective view of the die;

Fig. 3 shows a piece of stock upon which the die has operated; and 1Fig. 4 is a detail in transverse section on the line 4% of Fig. 1.

I have chosen to describe the invention as applied to a die for cuttingfrom such stock as leather, shown at S in Fig. 8 of the drawings, narrowstrips 8 having parallel opposite sides and beveled ends, which stripsmay be used for the shank welts of shoes. For this purpose my improveddie includes opposite side walls 10, 10 each having at its lower portiona cutting edge 12.

Patented Apr. 19, 1921. Application fi led December 17, 1918. Serial No.267,176.

Secured to the of these walls by screws 1a and pairs of pins 16 are endwalls 18, of less length peripherally of the die than the s de walls andhaving corresponding cutting edges 20. These side and end walls give adie member having a continuous edge adapted to produce a rectangularstrip. The side walls are bridged by an enlargement 22 upon the lowerend of a handle or pressurereceiving member 24 secured to the wallsbyscrews 26. V

.Along the inside of the opposite guideways 28 to receive flanges 30 g ksidewalls, pref-l erably parallel to the cutting edges 12 are upon apair ofcutting members 32,32. At the outer side of each member towardthe corresponding edge 20 oftheend wall and lying 111 the plane thereofis a cutting edge at inclined downwardly from the guideway.

Pivoted at seen each cutting member through an elongated slot 38. at itslower extremity is a link 40inclined upwardly and outwardly to a spindle42 by which it is pivoted just below the upper edges of the ing thelinks and walls 10 serve to-hold the cuttingmembers 32 at their normalinward positions farthest removed from the edges of the end walls. i p vExtending axially of the handle from the enlarged end is a bore 48 inwhich is mount- I side walls. Springs 44 surrounding the;

ed for reciprocation a plunger 50 having a cylindrical end portion 52 ofgreater diame ter than the remainder of the plunger, this portion 52operating within a counterbore in the handle. The enlargement 52. isthreaded at 56, and engaging this thread and secured frictionallyagainst tree rotation thereon by a screw 58 and contact piece 59 is ablock 60 furnishing the actuating portion of the plunger. At the outerends and on the upper side of the block are downwardly inclined sur aces(32 arranged to contact with antitriction rolls 6% mounted to turn uponthe links etO below their pivotal points 42 Engaging the thread 56 ofthe plunger at its lower extremity is a contact member 68, the outer endface of which is forced into proximity with the plane of the cuttingedges 12 and 20 of the die by a spring 72 surrounding the smallerportion ot' the plunger and being situated within the counterbore. Themovement of the plunger is limited by a flange Tet at the top of thecontact member 68, this striking the inner end of a screw 76 threadedthrough one of the side walls 10 and locked by a nut 78.

In using this die, the workman, grasping the handle 2%. places thecutting edges 12 and 20 upon the stool: to be cut and strilres the upperend of the anvil *ith a mallet or brings down upon it the beam of apress. As the cutting edges are forced through the stock, the member 68is held against. movement by the stock, the spring 72 yielding to permitthe walls of the die with cutting members 32 to travel past it. By thisrelative movement the rolls 642 are caused to descend the inclines 62o1": the actuating portion or the plun er. resulting in their beingswung outwardly about the spindles 1-2, moving the members 32 in theirguideways. The vertical and lateral movements cause the cutting edges 34to enter the stock and pass through it in a direction which is aresultant of the combined travel. The angle of the surfaces 62 is suchthat the horizontal component is greater than the vertical, and when thecutting edges 12 and 20 have severed the stock, the edges 3 1- are inclose proximity to the ed es 20, removing a wedge-shaped end portion,indicated at e in 3, at each extremity of the welt strip 8, thus givingthis the desired bevel. By altering the position of the block 60 alongthe threaded portion of the plunger when assembling the parts of the dieand by turning the contact portion 68, this latter operation beingtacilitated by a slot 80 at its lower extremity to receive a screwdriver, the operation or" the cutting members 32 may be controlled togive the desired extent of travel from their normal positions toward theedges 20 and at the proper time. When the operating pres sure upon thehandle ceases and the die is withdrawn from the stock, the spring 72restores the plunger to its normal position, this acting as an ejectorto remove the cut piece from between the die walls.

Having thus described the invention, what is claimed as new and desiredto be secured by Letters Patent of the United States is 1.
